    Syntheses and Structures of the Crystalline, Highly Crowded 1,3-Bis(trimethylsilyl)cyclopentadienyls [MCp″3] (M = Y, Er, Yb), [PbCp″2], [{YCp″2(μ-OH)}2], [(ScCp″2)2(μ-η22-C2H4)], [YbCp″2Cl(μ-Cl)K(18-crown-6)], and [{KCp″}]
    摘要:
    Yttrium and the smaller group 3 and 4f metal homoleptic M(III) cyclopentadienyls [MCp ''(3)] (Cp '' = [eta(5)-C5H3(SiMe3)(2)-1,3](-) and M = Y (1Y), Er (1Er), or Yb (1Yb)) were prepared from YCp '' I-2 (2Y) or the appropriate [LnCp '' I-2(thf)] and KCp '' in satisfactory (1Y), very low (1Er), or low (1Yb) yield. Attempted reaction of [ScCp '' I-2(thf)] with KCp '' failed to produce the homoleptic Sc(III) cyclopentadienyl. Compound 1Yb was synthesized in better yield by the redox reaction between [YbCp ''(2)(thf)] and either [PbCp ''(2)] (3) or the in situ prepared HgCp ''(2) (4) analogue. Complexes 3 and 4 were obtained by a salt metathesis route, 3 was isolated as a crystalline solid, while 4 was used only as a hexane solution. The structures of crystalline 1Y, 1Yb, 3, [{YCp ''(2)(mu-OH)}(2)] (5Y) [prepared by hydrolysis of 1Y], [(ScCp ''(2))(2)-(mu-eta(2):eta(2)-C2H4)] (6) {isolated in low yield from the reaction of ScCp '' I-2 (2Sc) with [K(18-crown-6)](2)[C6H2(SiMe3)(4)-1,2,4,5]}, [LaCp '' Cl-2(mu-Cl)K(18-crown-6)] (7La) {obtained from the foregoing potassium reagent and [{LaCp ''(2)(mu-Cl)}(2)]}, [YbCp '' Cl-2(mu-Cl)K(18-crown-6)] (7Yb), and [{KCp ''}(infinity)] (8) were determined by X-ray diffraction.

    摘要:
    用过量的NaI在无水THF中处理[{(Me 3 Si)2 C 5 H 3 } 2 LnCl] 2,或LnCl 3的混合物与两当量的[(Me 3 Si)2 C 5室温下在无水THF中的H 3 ] Na生成五种新的单体配合物[(Me 3 Si)2 C 5 H 3 ] 2 LnI(THF)(Ln = La(1),Sm(2),Y(3) ,Er(4),Lu(5)),收率可达50-69%。还以类似方式制备了混合的π-配体络合物[{(Me 3 Si)2 C 5 H 3 } {(Me 3 Si)C 5 H 4 }] Lul(THF)(6)。通过元素分析,IR和MS光谱,1 H NMR(对于抗磁性金属)和单晶X射线衍射研究(除1外)对化合物进行了全面表征。在每种化合物中,C 5环质心,THF氧原子和碘化物配体描述了金属周围扭曲的四面体几何形状。金属-碘键距离的变化不如金属-碳键和金属-氧键距离的变化可预测。
